The Murder of the Young Master

PLOT….Aile is one of the best assassins from the infamous Black Rose group.
One day, she receives a secret mission worth ten million gold.

The mission?
She must disguise herself as a maid and kill Lys Cassio—the only young master of the Cassio Dukedom, also called the “Monster Duke’s family” in the Livde Empire.

But there’s a problem:
No assassin has ever survived after entering the Cassio mansion.
Aile refuses at first… until she hears the reward is all in cash.

So she accepts, pretending to dream of being a maid.
Her mission is to win the young master’s trust, uncover his secrets, and finally take his life.

But instead of suspicion, Lys starts treating her like his personal helper:
“Clean the guest room.”
“Massage my shoulders.”
“Sing me a lullaby.”

Although annoyed, Aile plays along.
Until one day—
Lys looks at her with burning eyes and says:

“Aile, be mine. I can’t live without you.”

Did she… go too far in pleasing him.
